Title: Improvements in or relating to sack filling devices
IPC: B65B39/10
Filed: 1938-03-09
Abstract: 499,161. Weighing - apparatus; sack holders. MIAG MUHLENBAU UND INDUSTRIE AKT.-GES. March 9, 1938, No. 7318. Convention date, March 10, 1937. [Class 143] [Also in Group I] In a sack-filling machine wherein an automatic weigh - ing and filling device controls the release of a sack holder, a time lag relay is interposed between the automatic weighing device and the sack holder, so that this is only released after a predetermined period of time to allow for filling of the sack by discharge of the automatic weighing device. As shown, two automatic weighing machines each having a tiltable scale pan 2 discharge down a common shoot 1. The sacks are clamped to the bottom of the shoot by two holding jaws 20, Fig. 2, secured to levers 19 which are connected by bell-crank levers 23 and links 24 to the core of an electromagnet 25. The feed gates 7 of the weighers are retained in open position by arms 9, but are alternately closed by feelers 11 so that only one scale pan may be filled at a time. Pawls 12 lock the pans against tilting and thereby discharging their contents, until released by electromagnets 16. In operation, when the operator depresses a pedal 31, a double switch 29, 30 operating in conjunction with three-phase leads 36, a transformer 28 and high voltage leads 38, 39, establishes a circuit through the transformer 28 and timecontrolled relay 32 to close a double switch 33. The armature of the switch 33 closes the threephase circuit 36, 37 through the electromagnet 25 which then closes the clamping jaws 20 on to the sack. The current also operates one of two switches 34, 35 to close one of the high voltage circuits 39, 41 or 38, 40 and energize the corresponding electromagnet 16, thereby removing the corresponding pawl 12 to allow its scale pan to discharge. After sufficient time has elapsed for the material to pass into the sack, the time-controlled relay 32 breaks the circuit 36, 37 of the electromagnet 25, thus releasing the sack holding clamps 20. A new sack is applied to the shoot 1 and is clamped by again depressing the pedal 31, a similar cycle of operations then taking place in connection with the second weigher.

Abstract: 790,396. H.F. section apparatus. SIEMENSREINIGER-WERKE AKT.-GES. March 12, 1956 [March 11, 1955], No. 7737/56. Class 81 (2). In order to provide alternatively a continuous H.F. oscillation for cutting purposes or trains of damped oscillations for coagulation, the oscillation generator of an H.F. section apparatus may be switched to operate either as a free oscillator or as a blocking oscillator. The feedback coil L2 is normally connected to a point between a high resistance R1, connected to the H.T. supply, and a condenser C3, the time constant of which combination is such that the grid is always maintained positive and continuous oscillations are produced. These are passed over a potentiometer R2 to an amplifier V2 and thence to the cutting electrode K. For coagulation purposes a relay A is energized by foot or hand switches F, H, whereupon a large condenser C2 is connected in parallel with C3 to cause the valve VI to function as a blocking oscillator, and produce trains of damped oscillations. Energization of the relay A simultaneously substitutes potentiometer R3 for R2 so that the two types of output can be independently controlled. If desired, the hand switch for effecting the change-over of output may be incorporated in the electrode hand piece.

Title: Improvements in and relating to the cracking or distilling of hydrocarbon oils
IPC: C10G9/40
Filed: 1929-03-09
Abstract: 307,511. Magnus, H. March 10, 1928, [Convention date]. Hydrocarbons, cracking and distilling. - In apparatus for the cracking of hydrocarbons, the temperature of the heating zone is automatically maintained constant by thermostatic devices controlling the supply of raw matetrial to this zone. Cold oil passes from a tank 1 b a pump 2 and cock 4 to a coil 6 and nozzle 7 immersed in molten metal in a vessel 5. The oil may pass alternatively by a pipe 9 to a pre-heating coil 10 and a hot oil container 11, from which it is circulated by a pump 13 through a cock 14 to the cracking vessel 5 as before. A thermostatic control 15 immersed in the molten metal controls through relays of known type the cocks 4 and 14, so that a rise of temperature opens the cock 4 and partially closes the cock 14, thereby supplying a colder raw material. In an alternativeform cold oil passes through a coil in the cracking vessel into the hot oil storage tank, from which the hot oil is pumped to the distributing nozzle in the molten metal. A thermostatic device controls the flow of oil through the coil and through the nozzle, the two rates of flow being independent. The control systems may be applied to other types of cracking apparatus.
